Das im Stand der Technik beschriebene Ansaugsystem arbeitet in einem bestimmten Durchflussbereich.The intake system described in the prior art operates in a certain flow range.
Der Erfindung liegt die Aufgabe zugrunde, eine Rohluftleitung mit einem Abscheidesystem zum Abscheiden von Flüssigkeit aus einem Luftstrom eines Ansaugsystems für eine Brennkraftmaschine eines Kraftfahrzeuges zu schaffen, welches einfach aufgebaut ist und eine hohe Abscheideleistung sicherstellt.The invention has for its object to provide a raw air line with a separation system for the separation of liquid from an air flow of an intake system for an internal combustion engine of a motor vehicle, which is simple and ensures a high separation efficiency.
Diese Aufgabe wird durch die Merkmale des unabhängigen Anspruchs 1 gelöst.This object is solved by the features of independent claim 1.
Der wesentliche Vorteil des Abscheidesystems liegt darin, dass lediglich ein Auslass nach einer Krümmung einer Einlassleitung vorgesehen sein muss, welcher den Querschnitt der Leitung nicht oder nur unwesentlich verringert. Dieser Auslass ist derart zu gestalten, dass die abzuscheidende Flüssigkeit nicht von dem Luftstrom mitgerissen werden kann. Der Auslass kann als Vertiefung gestaltet sein, er ist dort anzuordnen, wo sich aufgrund der Krümmung und der Luftumkehr die Flüssigkeit aus dem Luftstrom aufgrund der Fliehkraftwirkung niederschlägt und entfernt werden kann. Gemäß einer Ausgestaltung der Erfindung besteht der Auslass aus einer Querschnittsvergrößerung der Leitung. In diese Leitung ragt ein Schälkragen hinein, welcher gemeinsam mit der Querschnittsvergrößerung eine Auslassrinne bildet. Der Schälkragen ist beispielsweise als Flügel ausgestaltet, welcher den Luftstrom ungehindert passieren lässt, allerdings dafür sorgt, dass abgeschiedene Flüssigkeit nicht mehr von dem Luftstrom mitgenommen werden kann.The essential advantage of the separation system is that only one outlet must be provided after a curvature of an inlet line, which does not or only slightly reduces the cross section of the line. This outlet is to be designed such that the liquid to be separated can not be entrained by the air flow. The outlet can be designed as a depression, it is to be arranged where, due to the curvature and the air reversal, the liquid from the air flow due to the centrifugal effect is reflected and can be removed. According to one embodiment of the invention, the outlet consists of a cross-sectional enlargement of the line. In this line, a peeling collar protrudes, which forms an outlet channel together with the cross-sectional enlargement. The peeling collar is configured, for example, as a wing, which allows the air flow to pass unhindered, but ensures that separated liquid can no longer be taken along by the air flow.
Zweckmäßigerweise ist der Schälkragen mit einer Umkehrfläche versehen. Der Auslass hat gemäß einer weiteren Ausgestaltung eine Flüssigkeitsauffangzone, die ebenfalls dafür sorgt, dass die Flüssigkeit nicht mehr in den Luftstrom umgelenkt werden kann. Die Flüssigkeitsauffangzone ist mit einem Wasserablauf versehen.Conveniently, the peeling collar is provided with a reverse surface. The outlet has according to another embodiment, a liquid collecting zone, which also ensures that the liquid can not be deflected into the air flow. The liquid collecting zone is provided with a water drain.
Weiterbildungsgemäß ist der Flüssigkeitsauslass mit einem Auslassventil verschlossen. Dieses Ventil öffnet beispielsweise bei einem bestimmten geostatischen Druck.According to training, the liquid outlet is closed with an outlet valve. This valve opens, for example, at a certain geostatic pressure.
Das Abscheidesystem wird bei einem Ansaugsystem für eine Brennkraftmaschine eines Kraftfahrzeuges verwendet. Dort ist es in der Rohluftleitung angeordnet, und zwar unmittelbar nach dem Einlass für die Rohluft. Dieser Einlass ist als abgewinkelte Ansaugtulpe gestaltet.The separation system is used in an intake system for an internal combustion engine of a motor vehicle. There it is located in the raw air line, and directly after the inlet for the raw air. This inlet is designed as an angled intake bell.
Diese und weitere Merkmale von bevorzugten Weiterbildungen der Erfindung gehen außer aus den Ansprüchen auch aus der Beschreibung und der Zeichnung hervor, wobei die einzelnen Merkmale jeweils für sich allein oder zu mehreren in Form von Unterkombinationen bei der Ausführungsform der Erfindung und auf anderen Gebieten verwirklicht sein und vorteilhafte sowie für sich schutzfähige Ausführungen darstellen können, für die hier Schutz beansprucht wird.These and other features of preferred embodiments of the invention will become apparent from the claims and from the description and the drawings, wherein the individual features are realized individually or in each case in the form of sub-combinations in the embodiment of the invention and in other fields and can represent advantageous and protectable versions for which protection is claimed here.

Innerhalb des Gehäuses befindet sich ein Schälkragen 19. Dieser Schälkragen 19 verringert den Durchtrittsquerschnitt für die durchströmende Luft nur geringfügig und läßt zwischen Wand 16 und der Vorderkante 20 einen Durchtrittsquerschnitt 21 offen. Dieser Querschnitt ist so hoch bemessen, dass selbst bei einem erhöhten Flüssigkeitsanfall diese Flüssigkeit aufgenommen werden kann. Nach diesem Durchtrittsquerschnitt ist eine Flüssigkeitsauffangzone 22 vorgesehen, diese Zone dient gleichzeitig zum Sammeln der Flüssigkeit und zum Zuführen derselben zu dem Wasserablauf 18. Der Schälkragen 19 weist eine Umschlagkante 23 auf, welche an ihrem Ende scharfwinklig zu der Schälkragenwand abgewinkelt ist. Durch diesen Aufbau wird ein Zurückfließen der abgetrennten Flüssigkeit in den Luftstrom verhindert. Die von der Flüssigkeit abgetrennte Rohluft verlässt das Abscheidesystem 10 gemäß dem Pfeil 24 und gelangt als nächstes zu einem Luftfilter.Within the housing is a peeling collar 19. This peeling collar 19 reduces the passage cross section for the air flowing through only slightly and leaves between wall 16 and the front edge 20 a passage cross-section 21 open. This cross-section is so high that even with an increased amount of liquid this liquid can be absorbed. After this passage cross-section, a liquid collecting zone 22 is provided, this zone serves simultaneously for collecting the liquid and for supplying the same to the water outlet 18. The peeling collar 19 has an envelope edge 23, which is angled at its end at right angles to the peeling collar wall. By this construction, a flow back of the separated liquid is prevented in the air flow. The raw air separated from the liquid leaves the separation system 10 according to the arrow 24 and next arrives at an air filter.
